Description: Behold the majesty that is the Buick Grand National. Forget about technology, the Grand National had it, but it was much more important as a means to change the public's opinion on turbocharging....

Carlos ElvroApr 26, 2013Being the owner of a true 10 sec gn ,
I love my gn, it's got a mean look to it
And performs great! I plan on getting at least 2 more

Roger SimasFeb 05, 2013As a current owner of an 1987 Grand National I can tell you there might be quicker cars now, but I can't go anywhere without people reacting to seeing a classic. In my 15 years of ownership no one has ever pulled up to race. It's a respect thing!

Alex ArvanitisNov 27, 2012Ya these were great in a straight line but I'd take a gto, Pontiac or preferably Ferrari, over one of these. Not bad cars by any means, but even in a gt car, I like compliant handling.
My buddy has one of these making big power, it's sketchy but wow

Colby ChurchNov 26, 20120-60 in 4.7 is faster than most 80's super cars.

Patrick SchalkNov 25, 2012Gah you guys need to chill out with the Ferrari comparos.

Alex ArvanitisNov 27, 2012And Chevy did good by not putting a 6 in the vette during those times. As a halo car, it would have hurt its image.
Gnx's in 87 could hit 60 in a best if 4.7, vettes were around 5.2, but 0-100-0 the vettes whooped gnx's. I love the gnx's turbo 6

Colby ChurchNov 26, 2012The late 70's and 80's were terrible years for the Corvette in terms of power. The oil crisis was going on at the time.

Paul TrahanNov 25, 2012This car would out run Vettes of the era with no problem until GM bumped the Vettes power.

Description: The Grand National didn't start off the monster it would become, and it took almost 10 years before Buick's turbo technology would be up to the task of turning out a good performance car. W...

Alex ArvanitisNov 27, 2012And variable valve timing.
I love the ls motors for their light, compact size. I'd swap one into anything from a miata to an r34 or mk4. Ls3 with a single= wow
But I love the dyno tuning I can do on my 5.4 4v swap. So adjustable/perfectable.

Alex ArvanitisNov 27, 2012A hot air gnx with the right mods can pull 10's easy. He probably does whoop on some late models cake.
Chevy has done an amazing job modernizing the ls series but big power is temperamental, one cam and boost don't allow for the flexibility of 4v's

Stephen IshardNov 26, 2012Every array of mustang and gt500 and wasn't the thunderbird only the corvette competition in the sixties

Colby ChurchNov 26, 2012Ford has always had the Mustang, but GM has had an arsenal of performance vehicles. And before you mention the Ford GT or any other type of race cars, I'm talking about cars most people can actually afford.

Colby ChurchNov 26, 2012That explains a lot. I like Ford to a certain extent, but GM just has a better history with performance cars. If Ford was smart, they would bring back the Thunderbird as a Corvette competitor, but they don't even try, probably because it's no use.

Jonathan GushueNov 25, 2012Maybe a Ford fanboy with a sore ass from prob getting beat by one. Or just a troll.

Tim PuckettNov 25, 2012@nick are you just gpnna be a dousche this whole article?

Alex ArvanitisNov 27, 2012A lot of motors can make 1500hp.
Al papito racing run 6's with a 323 ci 5.3 (debored and sleeved) 4v modular making 2000whp with off the shelf cams and common man affordable internals/turbo tech. They've gone 6.21@215+... It's the aeromotive car

Alex ArvanitisNov 27, 2012I plan to build a 1200whp c5 and am going to start with a 99 frc, because I'm going to change all suspension/etc. I'm pretty versed on parts I plan on and my motor build alone will top $25,000. A couple grand is not a smart/reliable build.

Alex ArvanitisNov 27, 2012Wow, a couple grand? No. My buddy's 1200whp c6 needed $35,000 in turbo, motor and cam mods.
A c5 ls6 is not much less.
You can make 1000whp once on te dyno for a couple grand but it won't last on stock internals and cam/heads.

Colby ChurchNov 26, 2012Not to mention the LS engines can make over 1509hp. Don't be a moron, I think GM executives know more about a car's worth and heritage than you do. Don't make ignorant comments, what GM did makes sense. The Corvette has 50 times the fanbase.

Colby ChurchNov 26, 2012@Nawwaf GM will never kill the Corvette. It's their pride and joy. And look how far it's come and where it's going. It's a super car killer for a fraction of the cost. I can go buy a 2002 Z06 for $22k and build it up to 900hp for a few thousand!

Colby ChurchNov 26, 2012@Nawaaf Are you stupid dude? The Corvette had been around since 1953, and you expect them to kill the Corvette over a car that had just came out and bore no resemblance? You're stupid. The Corvette is the flagship. The GNX is just another car.

Matthew CrightonNov 25, 2012Derp. How can GMC be a sub-division of GENERaL MOTOR COMPANY?

David ParentiNov 25, 2012Unless he meant General Motors Corporation...

William DownsNov 25, 2012Except GMC had nothing to do with Buick or the corvette, GMC is just a sub division of general motors

Jason BartlettNov 25, 2012Your buddy must be friggin rich or stupid lucky to have two gnx's! Buick only sent 547 cars to mclaren to have the gnx package installed. They are crazy rare , and worth a crap load

Tires were the major problem back then. Suspension tuning was soft though but 30 years ago, times were way different.
